This caught a few bugs/syntax errors (a few character classes were not
escaped properly in regex patterns, some indentation was illegal,
etc).

Generate version 2 of the block_image_update transfer list format.
This improves patch size by a different strategy for dealing with
out-of-order transfers. If transfer A must be done before transfer B
due to B overwriting A's source but we want to do B before A, we
resolve the conflict by:
- before B is executed, we save ("stash") the overlapping region (ie
the blocks B will overwrite that A wants to read)
- when A is executed, it will read those parts of source data from
the stash rather than from the image.
This reverses the ordering constraint; with these additions now B
*must* go before A. The implementation of the stash is left up to the
code that executes the transfer list to apply the patch; it could hold
stashed data in RAM or on a scratch disk such as /cache, if available.
The code retains the ability to build a version 1 block image patch;
it's needed for processing older target-files.
